4.7.8 Default Artifact Repository for Searching

The Griffon build assumes `griffon-legacy` to be the default Artifact Repository to be searched when querying for artifacts (either to list them, get some info or install them). This setting can be altered by specifying a value for `griffon.artifact.repository.default.search`. The value must be a valid repository name available in the configuration files.

For example, a local repository identified by the name '`my-local-repo`' can be set as the default search repository like so

    griffon -Dgriffon.artifact.repository.default.search='my-local-repo' install-plugin cool-plugin
